Re: Tilt hydrometer review

continued … So, here we have a snapshot of the graph three days in (50-70% of a similar brew in the Grainfather, fermentation does seem to like space and 20L or so is cramped it seems). Fermentation is close to finished. MynyddMynyllod1a.JPG You can pick out significant "stuck" events, there's one a...

Re: Tilt hydrometer review

I've a few more brews under my belt with the "Tilt", developing what I hope will be a consistent way to manage them. This last brew certainly helped! It was my first brew back in my big brewery that had been undergoing modifications for the past 14-15 months! I'm not very fast! I'd always thought th...

Re: Brewing alcohol free

This wine gum taste you mentioned would it be from the crystal additions I wonder. My "theory" is (okay, it's a hypothesis): The flavours do come from the crystal malt. There is a hint of the flavour in my "hot-mash" version (the "control"?). But … I reckon it's the apparent high protein content in...

Re: Brewing alcohol free

… As a continuation of the crystal malt discussion: I "convert" at a high temperature to preserve the dextrin in the crystal malt and not get it converted to "maltose" by beta-amylase. But I don't know if, and could not find any suggestion whether, dextrin in crystal malt is unconvertable by beta-am...

Re: Brewing alcohol free

We had our 5th Brecon last Saturday and a talk by WHC, a yeast provider who said he has a strain that only ferments a small range of the sugars available. He said they will not release it as brewerys who may us it would need very clean packaging as any bacteria would attack the remaining sugars. In...

Re: Brewing alcohol free

To help with the burnt issue I presume pre filtering before boil might be best. Nope! That's what I thought, and with continuous recirculation I have very debris-free wort. But the culprit is in solution, until heat denatures it and brings it out of solution. It's "hot break" but not like we are us...

Re: Brewing alcohol free

Being thinking about the issue of encouraging alpha amylase instead of beta. Under normal mashing at 64c/68c range we tend to opt for the low 5 PH range but in the cold mash scenario to produce low fermentables with some dextrins I'm thinking about flaring PH. Beta likes it best between 4.0 to 5.5 ...

Re: Starsan Discontinued ?

… It works by having a pH of less than 3 which the majority of bugs cannot tolerate. The likes of Starsan will have "surfactants" to make it "wetter" so bugs find it difficult to hide under microscopic layers of air (but they continue to hide very well under microscopic layers of grease and dirt). ...

Re: Starsan Discontinued ?

No final rinse. According to EU law, after using a sanitiser a final rinse is always required (for the pros). … I would not be surprised if the EU "definition" of sanitiser is out of step with what we've only just got used to using. You should be aware that "EU law" is one of the reasons the UK opt...

Re: Starsan Discontinued ?

This thread is in danger of muddying the principles of cleaning/sanitising so I reckon a brief summary is in order so people aren't going away with the wrong ideas: Starsan is a "sanitiser", it has no active cleaning ingredients at all. It must not be used alone, but makes a great final rinse so you...

Re: Starsan Discontinued ?

Try ‘milk stone remover’ from agricultural shop ( phosphoric acid dilute to 2% or less) ... you may have to buy 20 litres but only about £20 .

Re: Starsan Discontinued ?

BrewUK is putting about a Star San clone called "Chemsan" ( https://www.brewuk.co.uk/chem-100.html ), also based on phosphoric acid. I doubt any of listed the ingredients in Star San got it banned. More likely the traceability of the ingredients has fallen under suspicion? (EDIT: Oops, didn't notice...

Re: Clean-in-place Spray Ball - ANY Fermenter/Keg

The "Blow-Tie" devices work perfectly as pressure release valves, so that should reduce the regular soakings I would get. I'll be sure to work one into the main CIP design. These devices are perfectly happy "wet", they were originally conceived for the likes of RO setups (I think?).

Re: Maxi cooler python pump

The noisy pump will have to go! I have a couple of water pumps from my old water cooled computer/server - Dtek dB-1s. Interestingly there doesn't seem to be a lot of cross-over with these technologies. Now we have cheap powerful noisy pumps, whereas back then (there isn't much call for them anymore ...
